I wouldn't blame him for leaving, but I don't think Colorado is a smart move. UC is in a real bind because of Nippert Stadium. Ideally we'd play at PBS, but if we can't fill Nippert it doesn't make any sense to make the move. It's hard to attract bigger conferences with no real support to speak of and sub par facilities.
He can stay at Cincinnati and continue to win though, and doing so has shown that it can land you a big job like Brian Kelly got. I'd be surprised if he took this CU job. Stick around another year or two and keep doing your thing, good jobs will always open up and he'll be on basically every wish list if he keeps it up here.
